rnoniq nine r012. CYLINDER LOCKS.

Application filed October 10, 1922.

To all whom it may concern:

Be it known that 1, JOHN B. FREYSINGER, a citizen of the United States, and a resident of Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Im rovements in Facing Rings for C linder ocks; and I do hereby declare the ollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in facing or rose rings for cylinder locks and more particularl to such as receive the flanged or heade end of the lock cylinder.

One object of the present invention is to so construct a facing or rose ring principall of a single piece of sheet metal or har ened steel that it will be difiicult or impossible to turn the cylinder in the door because of the fact that the cylinder bean is recessed in the ring and thus protected against such attacks, and that the beveled face of the ring will offer no hold for a Wrench, aside from the fact that the ring may be provided with a part or parts which enter a notched portion of the door to hold it a ainst any turning movement.

Vith this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings- Figure 1 is a view partly in section and partly in elevation illustrating the application of my improvements to a door.

Figure 2 is a front view of the ring, and

Figure 3 is a rear view of the same.

In the drawings 1 represents a fragmentar portion of a door having an opening 2 t erein to receive a cylinder lock 3 and the latter is secured by screws 4 with the casing 5 in which the bolt work of the lock is enclosed, and a notch or recess 6 (or two such notches) is made in the door so as to communicate with the opening 2 in the latter, for a purpose hereinafter explained.

My improved facing or rose ring is shown at 7 and comprises a single piece of sheet steel or hardened metal which is bent or formed into proper shape by punching and drawing. When the ring shall have been punched and drawn, it will comprise a base portion 8, a beveled peripheral portion 9 Serial No. 593,489.

and a depressed portion 10, the latter forming an internal shoulder 11. Prongs or fingers 12 project inwardly from the inner edge of the ring and enter the notch 6 (or two such notches in the event that it is thought desirable to provide two notches (5 instead of one) for the purpose of preventing rotation of the ring. The ring may be covered with a thin scalp 13 of a metal different from that of the ring.

The recessed portion of the ring receives the flanged or headed end 14 of the cylinder 3 and the shoulder 11 constitutes a seat for said flange or head 14, a portion of the scalp 13 entering between said flange or head and shoulder, and a portion 15 of said scalp may be made to overlie the back of the ring so as to be disposed between the latter and the outer face of the door 1.

M improved facing or rose ring may be quic ly and cheaply made and it provides, within itself, a re-inforced ring which is so formed in a single piece of sheet metal or hardened steel that it will be diilicult or impossible to turn the cylinder in the door, not only b reason of its engagement with the door t rough the medium of a projection or projections, but also because of the fact that the cylinder head is recessed in the ring and the beveled portion of the ring offers no hold for a wrench.

Having fully described my invention what I claim as new and desire to Secure by Letters Patent, is:

1. A facing ring for a cylinder lock formed in a single piece of hard sheet metal bent upon itself and providing at its inner edge portion a recessed seat for the flanged or headed end of a cylinder lock.

2. A facing ring for a cylinder lock comprising a single piece of hard sheet metal bent upon itself formed at its inner edge portion with a recessed seat for the flanged or headed end of a cylinder lock, and having a beveled peripheral portion.

3. A facing ring for a cylinder lock made in a single piece of hardened sheet metal bent upon itself and formed at its inner edge portion with a recessed seat for the flanged or headed end of a cylinder lock, and a thin scalp of a difierent metal covering said sheet metal hardened ring.

4. A facing ring for a cylinder lock comprising a single piece of sheet metal bent upon itself and provided at its inner edge portion w ith a rc c essed sgat for the flanged or heaidegl end fo f itaf iiylin fiidirfif' prox ia id 'in ferior ly' With 'a prj'ecfion dig posed appruxinmtely at right angles to the 5 rear face of the ring and having a part to enter a rem ss in :Fdoor adjacent to the opening in the (1001' Cylinder 100k.
